From 7b3dcbb8424a2625ea176cc54ee1ca7064286710 Mon Sep 17 00:00:00 2001 From: Russell Bryant Date: Thu, 2 Aug 2007 19:26:12 +0000 Subject: [PATCH] Merged revisions 77949 via svnmerge from https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r77949 | russell | 2007-08-02 14:25:14 -0500 (Thu, 02 Aug 2007) | 5 lines Fix the case where a dynamic thread times out waiting for something to do during the first time it runs. This shouldn't ever happen, but we should account for it anyway.
